Best chopping boards for reducing microplastics

You may have seen the videos on social media. Tiny curls of plastic appear on a chopping board as a knife slices through food, raising an obvious question:

Are plastic chopping boards releasing microplastics into our food?

The answer is yes — plastic chopping boards do shed tiny plastic particles during normal use. Recent scientific research has confirmed this happens every time knives cut into the surface. The more important question, however, is whether those particles are harmful to our health. At the moment, scientists don't know exactly what this means for our health.

At KindCasa, we believe that when there are simple alternatives made from well-understood materials, they are often worth considering.

Why your chopping board matters?

Unlike many kitchen products, a chopping board comes into direct contact with both your food and a sharp knife thousands of times during its lifetime. Every cut wears away a tiny amount of the surface.

What should you choose instead?

If you're replacing a plastic chopping board, the good news is that the healthiest choices are also some of the simplest.

For most households, we'd recommend choosing a solid hardwood chopping board. It won't release microplastics during normal use, it's gentle on your knives, and with a little care it can last for many years.

Our favourite woods to choose

• Solid hardwood (especially acacia or beech)
• Solid bamboo = good budget alternative.

Other materials we would avoid

• Soft woods (such as pine) - They scratch and dent easily, creating deep grooves that are harder to keep clean.
• Bamboo fibre or wheat straw boards - Despite the natural-sounding names, these are often plastic composites, with plant fibres mixed into plastic resins. They're very different from solid bamboo and don't offer the same simple material benefits.
• Wood-fibre composite boards - These are convenient and often dishwasher-safe, but they're made by binding wood fibres together with resin. They're a practical option, but we wouldn't choose them over a solid hardwood board if reducing unnecessary plastic exposure is your priority.
• Glass, stone and marble - These won't release microplastics, but they're extremely hard on kitchen knives and can make chopping less safe and less enjoyable.
• Stainless steel and titanium - These have become popular on social media, but we don't think they're a good everyday choice. They're noisy, very hard on knife edges and offer few practical advantages over a good wooden board.

Looking after a wooden chopping board

• Wash with warm, soapy water after use.
• Never leave it soaking in water or put it in the dishwasher.
• Dry it upright before storing.
• Every few months, apply a food-safe chopping board oil to help prevent the wood from drying out and cracking.
